I have a very very very extremely low self esteem. I fina myself extremely unattractive and sometimes I even hide my face because of it.
Do you really find yourself extremely unattractive or is it outside pressure?
I can see from your chart you're an introvert, which gives a natural aversion to the spotlight.
Also, looking at your chart, I just see a lot of opportunity/help for self growth and change and also partnership..you have an abnormally large 1st and 7th house.
With Pluto in the 10th house (the spotlight/career/how others see you) and your 8th house placements, transformation is a huge theme for you. Caterpillar turning into a Butterfly, the phoenix rising from the ashes.
Your Moon is also square your 8th house Sun which reinforces this transformative need that you have.
If you truly believe you have an aesthetic issue, in 2018 there are literally so many options available. Beauty tips, health tips, etc.
I just have a hard time believing anyone actually believes themself to be unattractive..usually the insecurity comes from trying to fit the beauty standards of the masses.
This is reflected by your Moon in the 11th semisquare your Venus. The 11th house represents large groups and institutions, including society as an institution, and the standards that follow. With your Moon here, your natural tendency is to place emphasis these constructs. The way to deal with your 11th house Moon, is not to attempt to dismiss your feelings..but instead you'll need to figure out ways to place yourself around the right crowd. And if you are around your tribe or the right people, and you still insecure, then you really want to look inward and maybe try to tap into the "glow up" energy..because it's available to everyone.
You're young too so it maybe that you haven't found your look now. I didn't have mine at your age and I wish I knew then what I know now.
